satellites

I continued working on the automatic detection of satellite trails in astronomical imaging, which is formally trivial, but quite non-trivial in the face of real data issues. In the Hough transform image below, the white trapezoidal dot in the upper left is the signal of a satellite trail.

This is a clear detection, but the transform involves doing of order one million medians of a thousand values each. That's not fast.
